It doesn't heat the water, just stores it. The stove in the kitchen heats it, or when that's not running there is an external Willis heater (about 4KW and instant for hands, or leave on longer for a shower). I know someone that fitted two Willis heaters in parallel for instant showers.
Copper so the flowing water doesn't corrode it. It might last 100 years. Ours is over 40 years old.
Though a dual "immersion" heater (sink/bath) fitted in the tank for when main heating (stove, oil, gas etc) is of is more common. The Willis is the best electrical hot water heater, inexpensive and easy to retrofit to any "hot tank" or boiler.

It was invented in Northern Ireland.
There are people that have "boiler tanks" too. Less common in the past.
